ABSTRACT
Abstract Tillaux fractures are fractures of the lateral margin of the distal tibia, usually reported in children between 12 and 14 years old. As intraarticular fractures, they require anatomic reduction and fixation to avoid posttraumatic complications. Since the injury mechanism is external rotation of the foot on the leg, these injuries are commonly associated with other fractures or ligamentous lesions. Currently, arthroscopy is being increasingly used to assist and improve surgical treatment of ankle fractures. The authors describe a 12-month follow-up of a rare case of a missed Tillaux fracture associated with syndesmosis injury in a 76-year-old polytrauma patient, successfully treated by arthroscopically-assisted reduction and internal fixation.
Resumo As fraturas de Tillaux são fraturas da margem lateral da tíbia distal, geralmente relatadas em crianças entre 12 e 14 anos. Como fraturas intra-articulares, requerem redução e fixação anatômica para evitar complicações pós-traumáticas. Como o mecanismo de lesão é a rotação externa do pé na perna, essas lesões são comumente associadas a outras fraturas ou lesões ligamentares. Atualmente, a artroscopia está sendo cada vez mais utilizada para auxiliar e melhorar o tratamento cirúrgico das fraturas do tornozelo. Os autores descrevem um acompanhamento de 12 meses de um caso raro de uma fratura não percebida de Tillaux associada a lesão por sindesmose em um paciente de politrauma com 76 anos de idade, tratado com sucesso por redução e fixação interna assistida por artroscopia.

Objective To evaluate the short-term outcomes and analyze the complications of medial unicompartmental knee osteoarthritis (MUKOA) treated by unicompartmental knee arthroplasty (UKA).Methods Retrospectively analyzed the patients suffered with MUKOA and registered into our department from Jul 2015 to Jan 2017.71 cases were enrooled in the study,of which 17 are male (19 UKA) and 54 are female (66 UKA).The general information,perioperative data,Hospital for Special Surgery (HSS) score,visual analogue score (VAS) and complications of the group were analyzed.Results Females were three times more than males (54∶ 17).The average age of female subjects was lower than that of male,the difference was significant (P ＜ 0.05).The rate of Osteoporosis of females was significantly higher than that of males (P ＜ 0.05).The operative time,length of incision,total overt blood loss and postoperative in-bed time were (54.06 ± 6.24) min,(8.56 ± 0.83) cm,(86.10 ± 5.44) ml,(3.51 ± 1.01) d,respectively.No significant differences were found between males and females (P ＞ 0.05).The preoperative,3 months and 6 months postoperative HSS scores were 45.2 ± 4.5,80.3 ± 5.7 and 88.4 ± 4.2,respectively.No differences were found between males and females (P ＞ 0.05).The preoperative,3 months and 6 months postoperative VAS scores were 6.6 ± 1.2,1.7 ± 0.7 and 0.5 ± 0.5,respectively.No differences were found between males and females (P ＞ 0.05).There were 2 revised cases,and the reasons for revision were infection and unstability caused by sport injury.Conclusions UKA is an ideal choice for patients with MUKOA,Especially for the ones older than 60 years.However,the corrections on lower-limb forceline and joint unstability are limited,thus,the indications for UKA should be controlled strictly.
ABSTRACT
Total ankle replacement (TAR) is considered as a treatment option for end stage ankle arthritis. This treatment was abandoned due to the early failure prosthesis in the past. However, with recently advancements in ankle prosthesis design and improved surgical techniques, TAR has made great progress and the indications are expanding. Many studies have shown acceptable mid term and long term results of TAR, and it is worth looking forward to the prospect. Advantages of TAR over arthrodesis include improvement in joint range of motion, better gait activity, and decreased incidence of adjacent joint arthritis. With the further development, TAR will be considered as gold standard for the treatment of end stage ankle arthritis instead of the ankle arthrodesis. However, there are still many problems of TAR need to be solved in this present stage of development, including higher economic costs, lower survival rate, and higher revision rate. Patients and surgeons should have confidence in TAR, also need to choose this treatment with careful consideration.
ABSTRACT
Objective To evaluate results and demonstrate problems of Scandinavian total ankle replacement (STAR) in patients with ankle arthritis and clarify its role as a growing alternatives to ankle fusion.Methods Retrospectively analyzed 43 patients who had total ankle replacement from May 1999 to January 2013.All cases were evaluated with interview focusing on pain,daily activities and clinical and radiologic examinations.The average age of patients was 46 (range,35 to 56) years old.Among these cases,9 patients suffered from posttraumatic arthritis,25 osteoarthritis,5 rheumatoid arthritis and 4 avascular necrosis of the talar body.All patients complained about ankle joint pain and swelling as well as limited ROM of joint.Results Mean follow-up was 6.7 (1.5 to 12 years) years.37 cases had complete follow-up.The average preoperative ankle score was 27.0± 10.5,pain degree score was 16.5± 12.8,joint function score was 10.6±7.4,ROM score was 8.2±5.2.The average preoperative ankle score was 86.5±13.2,pain degree score was 49.5±4.5,joint function score was 19.7±9.5,ROM score was 19.2±3.2.The indicatiors compared with preoperative,postoperative differences have statistical significance.The score of postoperative Kofoed were divided into excellent 35 cases,good 1 case and poor 1 case,excellent and good rate was 97.3％.The American orthopaedic foot and ankle society (AOFAS) scoring system was improved from 40.5 preoperatively to 80.6 postoperatively.No postoperative loosening or migrating of the prosthesis was noted.Conclusion It was demonstrated that the standardized and normalized operative techniques as well as operative tools closely matched to the prosthesis could achieve favorable outcomes according to the clinical and radiographic outcomes and overall acceptable cornplication rates in the present study.STAR was a choice for the patients with advanced osteoarthritis,posttraumatic arthritis,rheumatic arthritis and avascular necrosis of the talar body.
ABSTRACT
Objective To explore the clinical results of total ankle replacements with the Scandinavian Total Ankle Replacement (STAR) prosthesis for end-stage ankle arthritis.Methods Data of 73 cases with end-stage ankle arthritis who received Scandinavian total ankle replacement from January 2005 to May 2013 were retrospectively analyzed.They were 34 males and 39 females,with an average age of 59.6 years old (range,37-76 years old),average body mass index (BMI) of 25.3 kg/m2 (range,21.8-28.0 kg/m2).All patients were classified into stage-3 arthritis according to Morrey-Wiedeman.Kofoed,American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score and visual analog scale (VAS) were used to evaluate the function of foot and ankle.Patients with a hindfoot deformity below 10° were compared with those who above 10°;and patients above 55 years old were compared with those who below it.Results 5 replacement failed (2 liner ruptured and received replacement;2 metal components displaced,1 received TTC fusion and the other underwent revision with inferior tibiofibular joint fusion,the last patient suffered from deep infection and received the STAR removal and secondary fusion) in 73,and the rest were followed up for 12 to 110 months (average,55.2 months).59 patients were satisfied with or without reservations.The satisfaction rate was 80.8％ (59/73).The pre-op values of AOFAS,Kofoed,VAS and range of motion (ROM) were 46.6±3.5,43.0±4.7,8.7±0.7,34.4°±7.1° and the post-op values were 86.6±4.3,82.6±4.6,3.0±1.0,45.1°±8.2° respectively,and all were significantly improved compared with before.The AOFAS,AOFAS Function and ROM values of patients below 55 years old were 86.1±3.8,47.0±2.7,45.7°±7.0°,and the same values of patients above 55 were 86.7±4.6,46.8±3.1,44.9°±8.8°.The AOFAS,AOFAS Function and ROM values of patients with above 10° coronal deformity were 86.1±4.7,47.0±2.7,43.0°±7.7°,and the same values of patients below 10° were 86.8±4.2,46.8±3.1,46.1°±8.2°.There was no difference between the groups.Conclusion The STAR is the preferable surgical treatment option in patients with end-stage ankle arthritis,showing high reliability and effectivity in pain relieving and function improvement.
